Application

The dropout (swing out) fuse is an expulsion type and its main function is to protect Transformers on rural distribution network. It is also particularly useful for inaccessible Sub-stations where indication of fusing is of advantage.

Construction

The Drop out fuse set has single pole construction and shall be suitable for Vertical mounting.
